Thanks for all the feedback. I just purchased a Logitech m525 mouse. It appeared that this is one of the few Logitech models that says MAC on the box. I got it home and was hoping to load their SetPoint software in order to re-program the mouse. It turns out that SetPoint is Windows only and the only gesture that this mouse supports in OSX is scrolling via the mouse wheel. BIG DEAL! What a major disappointment. I use Magic Perfs on my Apple mouse and it lets me do all kinds of great things.
In particular, I want to reprogram the scroll wheel with actions for a left or right push of the scroll wheel and click of the scroll wheel. Anyone know of an app that will work in Mavericks to do this with a Logitech mouse?
